This page contains a version of Roget's thesaurus of words and phrases taken from Project Gutenberg. Roget's thesaurus is essentially a reverse dictionary that allows you to find words related to the meaning you have in mind. When you navigate to the Thesaurus, you will see the following landing page containing the main categories for how words are grouped together.
When you look up a word by clicking on a number, it will take a few seconds for your browser to scroll to the correct entry on the main thesaurus page. So please be patient. The image below shows the entry displayed after clicking on “66”.
You can also view the words in the thesaurus as lists. By clicking on one of the letters under the page header, you will be presented with a list of words starting with that letter.
